Answer:
Step-by-step explanation:
- Total students = 100
- Failed and didn't appear = 10 + 7 = 17
- Total passed = 100 - 17 = 83
- Passed in Science and in Math = 80 + 71 = 151
- Passed in both subjects = 151 - 83 = 68

f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10
Step-by-step explanation:
interchanging the variables
x = 5y^2 + 10
5y^2 +10 = x
5y^2 = x - 10
dividing by 5
5y^2/5 = x/5 + -10/5
y^2 = x/5 + - 10/5
y^2 = x/5 - 2
y = 5 (x-10) 0/5 (sq.rt)
g(5x^2 + 10) = 5x/5
g(5x^2 + 10) = x
f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10
Answer:
b i think
Step-by-step explanation:
also this isnt 100 points lol. its 5
